Tension/compression asymmetry in yield and creep strengths of ni-based superalloys

Abstract:

The tension/compression asymmetries of yield and creep strengths of three kinds of single-crystal superalloys-PWA1480, CMSX-4, and TMS-75 - and a DS superalloy, Mar-M247LC, were investigated at intermediate and high temperatures. In PWA1480, tensile yield strength was higher than the compressive strength from 20°C to 750°C From the TEM observation, it was found that the asymmetry of yield strengths is primarily due to the microtwin formation associated with a superlattice extrinsic stacking f...
